Dynare is a pre-preprocessor and a collection of GNU Octave and MATLAB routines which can solve, simulate and estimate non-linear models with forward looking variables. . In particular, in the field of computational economics, it is used for solving and estimating dynamic stochastic general equilibrium (DSGE) models. . This package is only useful to users having MATLAB installed on their machine. It contains the source of the MEX files and will recompile them using the existing MATLAB installation.
